Arsene Wenger has warned Arsenal fans not to expect any more pre-season signings after his solitary move in the summer transfer market to capture German keeper Jens Lehmann.

Instead, Wenger's priority before the new campaign starts next month is to ensure captain Patrick Vieira commits himself to a new contract.

The Arsenal boss will nevertheless need to be at his most persuasive to reassure Vieira of Arsenal's ambitions despite being hamstrung in the transfer market by the financial demands of the club's new stadium plans.

After all, Lehmann remains the club's solitary summer acquisition for #1.5m, just a fraction of the amount invested by London rivals Chelsea since the arrival of Roman Abramovich.

However, Wenger insisted he was not worried by his lack of transfer activity, as he said: "I do not expect to sign any more players.

"We have lots of good young players and I am pleased with their attitude. It is a year when I wanted to integrate some of these players into the squad anyway.

"We saw them against Austria Vienna and we'll see them against Besiktas, and next week at Celtic and Rangers."

One of those experienced French stars is Vieira, who is due to return to training on Wednesday with just one year left on his existing contract. Although Vieira has constantly declared his loyalty to the club, he has also warned that failure to agree terms before the new season starts would leave the club at risk of him leaving on a Bosman free transfer 12 months later.

Wenger added: "There's no news yet. It is all going well but as long as it is not signed, it's not signed. But I am always optimistic so I am not really concerned."

Wenger has always stated that his two summer aims were to keep his squad together and to sign another keeper, with German international Lehmann at least having filled the second requirement.

As well as Vieira, Arsenal are still in talks with Sylvain Wiltord over a new deal, with French clubs Lyon and Paris St Germain both reported to be considering a #5m bid for the striker.

Wiltord is said to be seeking another three years at Highbury, rather than the two supposedly offered to him, but Giovanni van Bronckhorst says he's staying.

Despite apparent interest from Celtic and PSV Eindhoven, he said: "It is hard for an ex-Rangers player to sign for Celtic, but I have no intention of leaving Arsenal. I am very happy here and I am feeling as fit as ever."

With other fringe squad members, such as Kanu, Francis Jeffers and Ray Parlour also still at the club, Wenger's hands have been tied in the transfer market.

However, he insisted that his faith in youngsters such as Jermaine Pennant, Ryan Garry, Jeremie Aliadiere, Sebastian Svard, Philippe Senderos, Justin Hoyte and David Bentley is strong.
